I started a campaign by giving the players each 2 + their lore skill legends. Some were about items, and some locations, and some people depending on how their characters and backstories fleshed out. I.E. an Elf knew the legend of what Stenegrast (I know thats spelled wrong) was, a Aslene knew of Zeterome, everyone had some inkling about a ruin or some crap somewhere they could head towards.
It helped them feel like they lived in the world while also making new legends a reward. (there is a event in the book where if the players help some Raven Sisters the Raven Sisters tell them some legends in return).
I would never give the players ALL the legends. Then they are just a bunch of know-it-alls and nobody has anything they could be telling them and it cuts off one of my reward streams.
